Thank you all.
${ant.java.version} and ${java.version} yield two different values. 1.5 and
1.5.0_01, respectively.
I'm assuming ${ant.java.version} is the version Ant is using in case there
are multiple JDK's installed on the system and ${java.version} queries the
JAVA_HOME variable.
Am I correct?
Thanks again.

Subject: Re: Detecting JDK Version using ANT
Hello,
you can try with java.version property:
<project>
<echo>$${java.version} is ${java.version}</echo>
<echo>$${java.runtime.version} is
${java.runtime.version}</echo>
<!-- Dumps all properties starting with "java" -->
<echoproperties prefix="java"/>
</project>

Hi,
Is there a clean way to detect what version of Java
is being used when running a build file?
Some possible solutions include:
1) parsing the JAVA_HOME variable to detect the
version number
2) Checking the existence of a file which is
specific to a version
Both methods are somewhat brittle.
Is there a sureshot way of knowing whether ANT is
being invoked using Java 1.5 or not?
Thanks in advance,
Zarar
